Bluewater Flyfishing:
Cozumel is famous for the billfish run in the Yucatan channel. The months of: March, April, May and June offer the best bet for bluewater flyfishing. Sailfish, dorado, spearfish, white marlin and blue marlin are the main targets for the fly fisherman.
Plus some tunas, bonitos, barracudas, kingfish and wahoo around. There are some boats with flyfishing expertise in Cozumel, the Captain and mate(s) will help you tease this fish close to the stern so you can cast your fly at them.
The first flyrod world record ever for spearfish on a fly was caught in Cozumel waters, also the first (and only one so far) bluewater flyrod slam (Sailfish, blue and white marlin) was also caught in the Yucatan channel. A good proof that Cozumel´s bluewater flyfishing can get red hot anytime
